Question 1156835: By using the triangle whose sides have lengths 1, square root of 3 and 2, express the sine, cosine, and tangent of a 30-degree angle as ratios of these lengths. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! sin 30 is 1/2 or 0.5
cos 30 is sqrt(3)/2 or 0.8666
tan (30 is 1/sqrt(3) or sqrt(3)/3 or 0.5774
